Signature of two-electron interference in angular resolved double photoionization of Mg

Sokell, E; Bolognesi, P; Kheifets, Anatoli; Bray, Igor; Safgren, S; Avaldi, L


The double photoionization of Mg has been studied experimentally and theoretically in a kinematic where the two photoelectrons equally share the excess energy. The observation of a symmetrized gerade amplitude, which strongly deviates from the Gaussian ansatz, is explained by a two-electron interference predicted theoretically, but never before observed experimentally. Similar to the Cooper minima in the single photoionization cross section, the effect finds its origin in the radial extent and...[Show more]
